After some detective work, it looks like libstdc++ needs to be done before libsupc++ is done. I’ve added this dependency in r268377 and was able to do a full xdev build with a clean obj dir: rm -rf $HOME/F $MAKEOBJDIRPREFIX/mips-freebsd mkdir $HOME/F make xdev DESTDIR=$HOME/F XDEV=mips XDEV_ARCH=mips WITHOUT_CLANG=t WITHOUT_CLANG_BOOTSTRAP=t WITH_GCC=t WITH_GCC_BOOTSTRAP=t WITH_GNUCXX=t -j 20 Sean, can you see if this works for you now? And sorry about the cumbersome options. Those are in line to get fixed, but I wanna fix the build-in-tree issues first (which, alas, are harder than you’d think). I suspect that bapt’s src.opts.mk diffs are likely good candidates to be used committed too, but the above works w/o it. Also, I just built the binaries, I didn’t see if they worked.
